Fig. 2: Fetal fraction amplification (FFA) increases FF for 99.8% of samples tested and most appreciably for low-FF samples.

From: High-throughput fetal fraction amplification increases analytical performance of noninvasive prenatal screening

Fig. 2

The fold-change difference in FF as a result of applying FFA is plotted for individual samples as a function of the original FF without FFA. The dashed line indicates no change in FF, and samples in the purple-shaded region had increased FF with FFA.
